I think a lot of people feel that way because of how they developed Renee's character. She allows the audience to see Jack and understand him without having to have seen other seasons. She is a great new character (not just because Annie Wershing is amazing) that we have never had before. I have been a fan since day1, but never have I been so captivated by a single character, other than Jack, since Michelle (and her relationship with Tony). Renee is definately a great character, and I'm so glad you think so too, and can provide these for people like me =D
